压力感受器反射的主要生理机能,在于对中枢心血管神经原的紧张活动呈现抑制性控制作用.溯自1866年Cyon和Lndwig发现主动脉(减压)神经以来,这一反射体系作为维持动脉血压相对恒定的强大控制机制已为学者们所公认. 一、颈动脉窦一主动脉弓去神经支配所致的高血压 1927年Hering曾发现,切除颈动脉窦一主动脉弓区的神经支配,可引起动脉血压急剧增高.随后有人又证示,切除这些区域的神经支配会招致慢性
The main physiologic function of the baroreflex reflex is its inhibitory control of the nervous activity of the central cardiovascular neuron.1 Since Cyon and Lndwig discovered the aorta (decompression) nerves in 1866, this reflex system, as a means of maintaining arterial blood pressure Constant and powerful control mechanism has been recognized by scholars.A carotid sinus - aortic arch denervation caused by hypertension Hering 1927 had found, excision of the carotid sinus aortic arch area of the innervation, can cause a sharp increase in arterial blood pressure It was subsequently confirmed that the removal of the innervation of these areas can lead to chronicity
